We're dividing 7300112 by 449 
The aim is to understand the frequency of 449 in 7300112.

Step 1:
449 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 449

Let's proceed to step 2:
When dividing 73 by 449, we get 0 with a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 73 to get 73.
Take the next digit (0) from the dividend and append it to 73, then repeat: 730 / 449

Advancing to step 3:
If we divide 730 by 449, we get 1 and a remainder of 281.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 449 away from 730, we end up with 281.
Bring next digit (0) of the dividend behind the 281 and repeat the process: 2810 / 449

Step 4:
If we divide 2810 by 449, we get 6 and a remainder of 116.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtract 2694 from 2810 to get 116.
Include the next digit (1) from the dividend after 116, then repeat: 1161 / 449

Advancing to step 5:
The number 449 fits into 1161 2 times, leaving a remainder of 263.
Write down 2 as next digit of the result. 
Result so far: 162.0
The remainder is 263 after subtracting 898 from 1161.
Fetch the next digit (1) from the dividend, attach it to 263 and continue: 2631 / 449

Let's proceed to step 6:
If we divide 2631 by 449, we get 5 and a remainder of 386.
Write down 5 as next digit of the result. 
Result so far: 1625.0
The remainder is 386 after subtracting 2245 from 2631.
Take the next digit (2) from the dividend and append it to 386, then repeat: 3862 / 449

Moving on to step 7:
3862 divided by 449 is 8 with a remainder of 270.
The next digit of our result is 8. 
Result so far: 16258.0
If we subtract 3592 from 3862, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 8:
449 can be fit into 2700 6 times, resulting in a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 16258.6
Deduct 2694 from 2700 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
449 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 16258.6
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 10:
If we divide 600 by 449, we get 1 and a remainder of 151.
Record the quotient 1 as the next digit in the result. 
Result so far: 16258.601
If we subtract 449 from 600, we get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Moving on to step 11:
449 goes into 1510 3 times with a remainder of 163.
The number 3 becomes the next digit in our result. 
Result so far: 16258.6013
Deduct 1347 from 1510 and we're left with 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Advancing to step 12:
The number 449 fits into 1630 3 times, leaving a remainder of 283.
Write down 3 as next digit of the result. 
Result so far: 16258.60133
If we subtract 1347 from 1630, we get 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

The final outcome is 16258.60133, with a leftover of 0.000283.
